ST0 aZZ whm it mayconcern: Be .itknown that I,- KNUT KLEVEN, a, ;1tizen ofthe -United States, -residing at Mount Horeb, the county of Dame and 5,Stateof.Wiscorisin have inventecl a new and useful Silo-Door Fastener of which the following is a specification.

ing fodder and.otherfoocl stufisfor -cattle. The objectof the invention is to provide a silo having a c011tinuous door way extending from the top to the bottom thereof so as to givenccess-theret at any height, and to obviate obstructiohs in the door way which 15.. w0i1ld interfere with the throwing -out of silage through said door way.

A further' object of the invention is to pro- 1 vide.iinprovecl means for locking the doors 1nclosed os1t1011s, a single lockmg means beingemp oyecl to eflectthe locking ef adjecent doors.

A still further object ofthe invention is generally to improve this class of devices so as to inerease thei1 utility, durability and efliciency.

Further objects end advantages Will appear in the followingdescription, it being understood that varous changes in form, proportions and minor details of construction ni.y be resorted to Within the scope of "the ap ende" claims.

In t e a= ompanying drawings forming a part of thi: spemficationz. Figure 1 is a. front elevatioi1 c a silo constructed inaccoidance -85 with my invention Fig. 2 is a vertical sectional view of 2, portion of the same. 1' 3 is a transversesectional view taken on the 1i11e33 of Fig. 2. Fig.4 is 21 detail pers ective view of one of'the fastening deinces etached. Fig. 5-is aijdetail sectional view showing the ma'nner of fastening the zo of one door section when en adjacent oor secti'on is removed. Fig. 6 is a per spective view of lockingcleat detached.

Similar numerals of reference indicate corresponding perts in all of the figures of the draWings. The improved silo forming the subject matter of the present inventon includes a 56 body portioh 5 preferably formed of wrtical Staves arra nged in cylinclrical form, as shown,

api1rt by transverse bars 8, the inner feces of the side membe'rs 7 being rabbeted at 9 and their outer feces provided with longitudinal grooves 10 for the reception of the adjacent staves of the body port-ion.

Interposed between the transverse bars 8 are a plurality.. of individual removable doors or elosures 11 each provided with a transverse reinforcing clea.t 12 W11icl1 baars against the longitudinal edges of the adjacent transvrse bars 8 and serves to suport the closures in position in the door frame. The reinforcing strips 12 are secured to tbie front 01 exposd feces of the door sec tions 1l and are prefe1ably of lessthickness than the transverse bars 8, sa'id strips being rigidly secured to the closures 11 bynails,

screws or siniilar fastening devices 13.

Secured to the lower edge of .each door or closure 11 is a strap iron 14 having its free end reduced and 0f set at 15 to form a looking bolt 16 adapted .t 0 enter 2,11 eye 17 carried by a. thraded bolt 18 secured to the adjacent transverse strip 8. The loolts-l8 pierce the transverse strips 8 and areeach preferably disposed with the eyes 17 interp.osed betvveen and projecting slightly"beyond the meeting edges of adjacent door sections 01 closures 11 as Best shown in Fig. 2 of the clrawings. 5ngaging the threacls on the bolts 18 are cl.ampii1g nuts 19 having terminal handles 20 by means of .whichithe bolts may be adjust to clamp "the eyes 17 in engagement with the reducd extensions 16 thereby te effectall lock;thedoon sec tions' 11 against acci ental displacement;

Thestrapyirons 14 are preferably securedto the inner feces of the door sections 11 While the.nuts 19 are erra ngecl on'tl1e outside of the silo so that the seme meybe conveni- "ently manipulated when it is desird to remove oneormore ofthe door sections to permit the introduction or removlofsilage or other fodder. The silo is; einforced and strengthened b the provision-of one or more=hoops 21, whio latter pass thrbugh suitable penings 22 fo'rmeglin the side-members 7 of the door frame and are provided withthe usual turn bnckles by means of"which the tension of the hoops may be adjusted.

As a means for locking the up er portion of one door seotion against inwar movement when an adjacent door seotion is removed, there is Provided a lockin bar or cleat 23 adapted to be positioned etween the side bars ofthe door frame, said loekin'g bar or cleat being rovideciwith a bolt 24 similar in construot1on to the bolt 16 and-alapted to enter the adjacent eye 17, as best shown'in Fi 6 of the drawing.

i extendirig the door ay the entire heig tof the silo and frming the olosure for the door Way in sections, access may behad to the interior of the silo at any desiied heighttha door'way anddoor seotions being so constructed asto aflord little or no obstructiori to the passageof the-fider in filli ng or emptying the-silo.

Attention is here called to the faot that the. outward movement of the door sections .;11 are limited by engagement with the -rabbeted edge 9 of the side members 7, while the vertical movement of said seotions are limited by the reinforcing strips 12 hearing against the transverse bars 8.

If desired a Suitable packing may be disosed at the rabbeted edge 9 of thedoor rame in order to insure an air and water tight packing for the door sections and thus 3;, fi revent deterioration of the contents of the Having thus desoribed the invention what isolaimed is:

'1. A silohaving a door way, a series of in- "dividual door seotions olosing the door way,

- anda fastening devioe interposed. btween the meeting edges of adjacent door seotions and for1hing a locking means for said sections.

2 A silo having a door way, a series of individual door sections closing the door way, bolts iiterposed between the meetin edges of adjacent seetions and provided W1th terminal eyes, and a locking member seoured to the lower edge 0f eaohsection and engaging the eye of the adjacent bolt. 3. A silo having a door way, a frame seated in the door way and provided With s aced transverse bars, a series of individual oor seotions fittingbetween the transyerse bars, and fastening devioes disposed at the meeting edges of adjacent'sections and forming a locking means for saidseotions.

4. A silo having a door Way', a frame seated =ii;rthe door way and inclnding spaced longiudinal members connected by transversebars, the inner ed es of the longitudinal members being rab tingbetween the transverse bars and bearihg against the rabbeted edg es,of the side threaded eted, door sections fit 'beyond the inner faces of the door seotions,
